Abstract

A device for finely cutting workpieces from a material (1), comprising a press plate (10) which is subjected to the pressure of a knife-edged ring cylinder (13) consisting of a knife-edged ring and a clipping punch (9) which is guided in said pressing plate (10), and associated with a blanking die (7) with a counter holder (16) (ejector) on a tappet, whereby said tappet (7) is placed against at least one compensation cylinder (22) which is hydraulically connected to the knife-edged ring cylinder.
